Microsoft Office 2019 and 2021 for Mac view-only conversion
Microsoft Office 2019 and 2021 for Mac view-only conversion
Microsoft Office 2019 和 2021 Mac 版将转为“仅查看”模式
From Consumer Rights Wiki Microsoft Office 2019 and 2021 for Mac view-only conversion (2026) is a scheduled remote degradation of perpetually-licensed Microsoft Office software for macOS and iOS, set for July 13, 2026 when a license-validation certificate used by the Office apps expires. 根据消费者权益维基（Consumer Rights Wiki）的记录，Microsoft Office 2019 和 2021 Mac 版“仅查看”模式转换（2026）是一项针对 macOS 和 iOS 永久授权版 Microsoft Office 软件的计划性远程降级措施，定于 2026 年 7 月 13 日生效，届时 Office 应用所使用的许可证验证证书将过期。
After Office 2019 for Mac reached end of support in October 2023, Microsoft assured customers their installed apps would “continue to function.” The July 13, 2026 conversion instead drops the apps into a Microsoft-defined “reduced functionality mode,” in which files can be opened and viewed but not edited or saved. By May 30, 2026, the original 2023 end-of-support page had been re-dated and rewritten on Microsoft’s site; the “continue to function” clause was removed. 在 Office 2019 Mac 版于 2023 年 10 月停止支持后，微软曾向客户保证其已安装的应用将“继续运行”。然而，2026 年 7 月 13 日的转换会将这些应用降级为微软定义的“功能受限模式”，在此模式下，文件仅能打开和查看，无法进行编辑或保存。截至 2026 年 5 月 30 日，微软官网已将最初 2023 年的支持终止页面重新标注日期并进行了重写，删除了“继续运行”这一条款。
Background
背景
Microsoft announced general availability of Office 2019 for Windows and Mac on September 24, 2018. In the launch blog post, Microsoft’s Jared Spataro wrote that “Office 2019 is a one-time release and won’t receive future feature updates,” positioning the product as the on-premises alternative to the Office 365 subscription. Contemporary Microsoft Store pages marketed Office Home & Student 2019 as a “One-time purchase for 1 PC or Mac” at $149.99, with copy that explicitly contrasted the perpetual product against the Office 365 subscription model: “One-time purchases don’t have an upgrade option, which means if you plan to upgrade to the next major release, you’ll have to buy it at full price.” 微软于 2018 年 9 月 24 日宣布 Office 2019 Windows 和 Mac 版正式发布。在发布博客中，微软的 Jared Spataro 写道：“Office 2019 是一次性发布版本，不会接收未来的功能更新”，将其定位为 Office 365 订阅服务的本地化替代方案。当时的微软商店页面将 Office 家庭和学生版 2019 宣传为“1 台 PC 或 Mac 的一次性购买”，售价 149.99 美元，并明确将该永久授权产品与 Office 365 订阅模式进行对比：“一次性购买没有升级选项，这意味着如果您计划升级到下一个主要版本，则必须全价购买。”
Office 2021 for Mac became generally available on October 5, 2021 under the same one-time-purchase model & is scheduled to reach end of support on October 13, 2026 per the Microsoft Lifecycle Policy. Office 2019 for Mac reached end of support on October 10, 2023. Office 2021 Mac 版于 2021 年 10 月 5 日以同样的一次性购买模式发布，根据微软生命周期策略，其支持服务定于 2026 年 10 月 13 日终止。Office 2019 Mac 版已于 2023 年 10 月 10 日停止支持。
Microsoft’s edited end-of-support assurance
微软修改后的支持终止保证
The June 3, 2023 snapshot of Microsoft’s end-of-support page contained this passage: “Support for Office 2019 for Mac will end on October 10, 2023. Rest assured that all your Office 2019 apps will continue to function—they won’t disappear from your Mac, nor will you lose any data. However, you could expose yourself to serious and potentially harmful security risks.” 2023 年 6 月 3 日的微软支持终止页面快照包含以下段落：“Office 2019 Mac 版的支持将于 2023 年 10 月 10 日结束。请放心，您所有的 Office 2019 应用都将继续运行——它们不会从您的 Mac 上消失，您也不会丢失任何数据。但是，您可能会面临严重且潜在的有害安全风险。”
By May 30, 2026, the same URL carried a new publication date of May 15th, 2026 and a shorter passage: “Support for Office 2019 for Mac ended on October 10, 2023. Rest assured that all your Office 2019 apps won’t lose any data. Your data can be accessed on any supported Microsoft 365 or Office product. However, you could expose yourself to serious and potentially harmful security risks.” 到 2026 年 5 月 30 日，同一网址显示了 2026 年 5 月 15 日的新发布日期，且段落缩短为：“Office 2019 Mac 版的支持已于 2023 年 10 月 10 日结束。请放心，您所有的 Office 2019 应用都不会丢失任何数据。您的数据可以在任何受支持的 Microsoft 365 或 Office 产品上访问。但是，您可能会面临严重且潜在的有害安全风险。”
The 2023 assurance that the apps would “continue to function” was removed; the data-safety clause was kept; a new sentence pointing owners to “any supported Microsoft 365 or Office product” was added. The 2023 wording was resurfaced in May 2026 by JimmyTech, a San Francisco IT consultancy, which characterized the July 2026 conversion as Microsoft “breaking that promise.” 2023 年关于应用将“继续运行”的保证被删除；数据安全条款被保留；并增加了一句指向“任何受支持的 Microsoft 365 或 Office 产品”的新句子。2023 年的措辞在 2026 年 5 月被旧金山 IT 咨询公司 JimmyTech 重新翻出，该公司将 2026 年 7 月的转换描述为微软“违背了当初的承诺”。
Certificate expiry mechanism
证书过期机制
Microsoft’s administrator documentation states that “Microsoft 365 apps use a digital certificate to validate licensing. The certificate currently in use expires on July 13, 2026. Apps that are updated to the minimum required versions already include the renewed certificate and continue to function normally. Apps on older versions enter reduced functionality mode after the certificate expires.” 微软的管理员文档指出：“Microsoft 365 应用使用数字证书来验证许可。当前使用的证书将于 2026 年 7 月 13 日过期。更新至最低要求版本的应用已包含更新后的证书，并将继续正常运行。旧版本的应用在证书过期后将进入功能受限模式。”
The minimum required builds are version 16.83 on macOS and version 2.93 on iOS, & those builds in turn require macOS 12 (Monterey) or later, or iOS 17.0 or later. Office 2019 has no fix. The product line is bounded by a hard build cap below the 16.83 threshold, and Microsoft’s own support documentation states the issue “cannot be resolved by updating or reinstalling Office 2019 for Mac.” 最低要求版本为 macOS 上的 16.83 版和 iOS 上的 2.93 版，而这些版本又要求 macOS 12 (Monterey) 或更高版本，或 iOS 17.0 或更高版本。Office 2019 没有修复方案。该产品线受限于低于 16.83 阈值的硬性版本上限，微软自己的支持文档也指出，该问题“无法通过更新或重新安装 Office 2019 Mac 版来解决”。
Office 2021 for Mac, by contrast, is still receiving updates through its October 13, 2026 retirement date & can reach 16.83 on supported macOS versions. Windows and Android versions of Office are not affected by the certificate expiry. 相比之下，Office 2021 Mac 版在 2026 年 10 月 13 日退役日期前仍会收到更新，并且可以在受支持的 macOS 版本上达到 16.83 版本。Windows 和 Android 版 Office 不受此证书过期的影响。
Reduced functionality mode
功能受限模式
After July 13, 2026, affected installs of Word, Excel, PowerPoint, Outlook, and OneNote on Mac, iPhone, and iPad will enter reduced functionality mode, in which Microsoft says users “can open and view files but can’t edit, save, or access full features.” Office 2021 for Mac and Microsoft 365 for Mac users on macOS 12 (Monterey) or later can avoid the conversion by updating to build 16.83. Office 2019 for Mac users have no update path. 2026 年 7 月 13 日之后，Mac、iPhone 和 iPad 上受影响的 Word、Excel、PowerPoint、Outlook 和 OneNote 安装将进入功能受限模式，微软称用户“可以打开和查看文件，但无法编辑、保存或访问完整功能”。运行 macOS 12 (Monterey) 或更高版本的 Office 2021 Mac 版和 Microsoft 365 Mac 版用户可以通过更新到 16.83 版本来避免转换。Office 2019 Mac 版用户则没有更新路径。
May 2026 customer notification
2026 年 5 月客户通知
Microsoft began emailing affected customers in mid-May 2026 about the upcoming change. PiunikaWeb, which published the earliest press coverage on May 16, 2026, characterized the user response as “largely negative.” The email included an offer of a free Microsoft 365 Personal trial that requires a payment method and converts to a paid subscription if not cancelled. 微软于 2026 年 5 月中旬开始向受影响的客户发送有关即将到来的变更的电子邮件。于 2026 年 5 月 16 日发布最早新闻报道的 PiunikaWeb 将用户反应描述为“主要是负面的”。邮件中包含一份免费的 Microsoft 365 个人版试用优惠，该优惠需要支付方式，且若不取消，将自动转为付费订阅。
Microsoft’s response
微软的回应
Microsoft directs affected users to three options: continuing to use the apps in view-only mode, switching to the free Microsoft 365 web apps, or paying for a Microsoft 365 subscription or a new perpetual Office Home 2024 license. Microsoft has issued no public statement reconciling the July 2026 conversion with the 2023 “continue to function” assurance. 微软为受影响的用户提供了三个选项：继续以“仅查看”模式使用应用、切换到免费的 Microsoft 365 Web 应用，或者付费订阅 Microsoft 365 或购买新的 Office 家庭版 2024 永久许可证。微软尚未发布任何公开声明来解释 2026 年 7 月的转换与 2023 年“继续运行”保证之间的矛盾。
Consumer response
消费者反应
AppleInsider’s Amber Neely, in a May 28, 2026 article, wrote that Microsoft “will be effectively bricking the standalone Office 2019 for Mac, iPad, and iPhone users on July 13, 2026.” JimmyTech framed the choice as discretionary: “But certificates can get renewed.” AppleInsider 的 Amber Neely 在 2026 年 5 月 28 日的一篇文章中写道，微软“实际上将在 2026 年 7 月 13 日让独立的 Office 2019 Mac、iPad 和 iPhone 用户设备变砖”。JimmyTech 则认为这种选择是主观随意的：“但证书是可以更新的。”
